TRANSFORMEB.

Specification of Letters Patent.. rPatelltd NOV. 2S, 1911.

Application filed January 10, 1908. Serial No. 410,214.

To (1H. whom tt may concern:

lie it known that l, l'lnnnicn'r C. SOULE, a citizen of theUnited States, and a resident of 'lilltiiislillig, in the county of Allegheny and State of Pennsylvania, have invented a new und useful Ii'nprovenicnt in Transformers, of which the following is a specification.

vcore and means for adjustably securing the assembled Winding to said core.

Figure l of the accompanying drawings is a sectional elevation of a transformer constructed in accordance with my invention. Fig. 2v is a plan View of a portion of the device shown in .Fig 1, and Figs. 3 and 4 are views of the assembled Winding With the core removed.

Referring to the drawings, the transformer here illustrated comprises a substantially rectangular core l having an innei` 4 portion Q on which awinding 3 is mounted and outer portions fl and 5 eachof which comprises a side and two ends to serve as a return circuit for the magnetic flux produced in the inner portion 2 by the Winding.

The winding 3 comprises a plurality of circular coils (3 which are spaced apart and clamped together by a frame 7 havingyrecltangular end members 8, longitudinal tie bolts t) and cross strips 10 that are inter posed between the adjacent coils 6. In this Way, the Winding is assembled and may be handled independently of the core Without danger ofinjury or relative displacement of its coils. The end members of the frame are provided with additional cross-strips 11 and 12 which are notched to engage an insulating sleeve or cylinder 13 vvhich surrounds the inner portion Q of the magnetizable core, thereby preventing lateral movement of the Winding, relatively to the core, in a horizontal plane.

l l l l i 'lhe core vl is preferably built up of soft iron or steel plates in a well known manner, and the assembled structure is held together by channel beams 1st and l5 and tie bolts 16. The laminated structure, formed as above indicated, is provided with ventilating spaces l? through which cooling fluid, such as air, may be forced during the operation of the transformer. The inner portion-of the core has substantially twice as great an area of cross-section as each of the outer portions fl and 5,` since the inner portion serves as a common path for the magnetic iiux which is divided as it passes through the outer portions. The section of the innei portion of the core is double cruciform in order to reduce the necessary diameter for the coils, of which the Winding is composed.` The Winding 3 issupported by acradle@`l block 18 of insulating material which .isf clamped to the core,l at one side and `is cen-1v, tered by insulating blocks 19 which are ad-' justably secured to thecor'e, at the opposite side, and may be drawn toward each other to force the coils against the block 18. The

spacing strips 10 serve to separate the adjacent coils of the Winding so that a circulationof air or other cooling fluid may be es tablished, the arrangement of parts preferably being such that separate bodies or currents of cooling fluid all flow through the spaces 17 in the core structure and through the spaces between-the coils which are provided by the strips 10.

The assembled transformer is inclosed in a suitable casing 20 and the transformer connections are established by short lengths of cable which are secured to the desired coils and extend out through the casing, being supported by bushings 21 of 'insulating niaterial or by collars according as the leads form high or low-voltage connections to the transformer.

It will be understood that Various modilirations in the size and arrangement of details may be effected within thev scope of my invention, and I desire that only such limitations shall be imposed as are indicated in the appended claims.

.I claim as my invention:

l. A transformer comprising av magnetizable core, a plurality of circular coils disposed thereon in substantially vertical planes, a cradle-block Which engages the the cradle-block.

lower outer edges of the coils, and adjustable means for engaging the upper edges of` the coils to force their lower edges against 2. A transformer comprising magnet-- izable core having an inner ybody portion and outer portions of substantially rectangular form,` a plurality of circular coils mounted on the inner body portion, nnd'relatively adjustable means adapted toengage the opposite outer edges of the coils to support them in vertical planes. l

3. A transformercomprising a substantially `rectangular magnetizable core having an inner ,body portion which connects the ends of the outer portions together, a plu rality of circular coils mounted on the inner body portion, a cradle-block of insulating material mounted upon one outer side portion to engage the .edges of the coils, and insulating blocksadjustably secured to the opposite outer side portion `to engage the edges of the coils. A

4. A transformer' comprising a core, a plurality of circular coils therefor, a spacing and clamping ramefor the coils, and an adjustable supporting cradle to engage the upper and lower outer edges of the coils and support them in vertical planes.

the outer 5. A transformer comprisin plurality of circular coils there or,a clamping frame for the coils comprising end members, spacing strips and tie bolts, land a supporting cradle for the assembled winding comprising blocks of insulating material adjustably secured to the core and adapted to embrace the edges of the coils -at opposite sides.

6; -A transformer comprising a substantially rectangular niagnetizable core having an inner portion that connects the ends of circular coi s mounted on the inner core por tion, a clamping frame for the coils that 1s inde endent of the .core and comprises end a core, a :J
